Simple Machines

A simple machine is something that is used when you are unable to apply enough force in order to lift an object. A machine allows you to lift heavy objects. Machines help you to lift large objects because they increase the distance which means less force is required. When you do not use a machine you are required to use much more force because the distance is extremely small.(F)(d)=(f)(D). This means that the work will be the same as well. work in=work out. Bill Nye is really good at explaining the different ways machines are used and how they work. He explains where the work in is and the work out. Bill Nye is awesome and I think that this video is really clear.
